Agreed. Prime 4 is a soulless game - by that I mean it doesn’t have a guiding ethos or soul as all the other Metroid/Prime games. The open area is empty and pointless, with the levels/dungeons being extremely linear and devoid of puzzles. It’s a Metroid game by name only.
Metroid Prime 4 Beyond fundamentally fails as a Metroid game. It is incredibly linear with its temples when they should be more complex interconnected with Sol Valley, Nintendo’s worst attempt yet at open-world (and doesn’t even fit the franchise). The characters are also really bad.
There’s a lot more I can say, I really hate this game. That doesn’t mean the Prime games should be thrown away to never be touched again. The original trilogy, especially the first two, are really good and there’s a lot of potential for a Prime 5 (especially a good one). Unfortunately bad games happen sometimes.
That being said, I’m still really excited for Metroid Ravenous, it looks very good.
